【摘要】：目的 :探讨脑微出血灶(Cerebral microhemorrhage foci,CMHF)的MRI多序列成像的影像特征与价值。方法 :对45例CMHF患者进行3.0T MRI多序列成像,将其影像学表现进行分析研究。结果:所有CMHF分为脑微出血(Cerebral microbleed,CMB)和灶性出血(Intracerebral hemorrhage,ICH):ICH 15例,急性脑挫裂伤或轴突损伤4例、高血压性或脑淀粉样血管病伴出血9例、梗塞区出血2例。CMB 30例,老年性微血管病或与多发性腔梗伴随的陈旧性出血16例,陈旧外伤史或无特别主诉及病史者14例,14例中有10例诊断为海绵状血管瘤。两类病灶表现为信号丢失,除SWI(100%)外,DWI也有较高的敏感性(80%)。结论 :多序列3.0T MRI对急慢性CMHF提供更多的病理信息,进而对疾病做出诊断、鉴别及进展预测。
[Abstract]:Objective: to investigate the imaging features and value of MRI multi-sequence imaging in intracerebral hemorrhage (Cerebral microhemorrhage foci,CMHF). Methods: the 3. 0 T MRI multi-sequence imaging was performed in 45 patients with CMHF. Results: all CMHF were divided into cerebral microhemorrhage (Cerebral microbleed,CMB) and focal hemorrhage (Intracerebral hemorrhage,ICH): ICH in 15 cases, acute cerebral contusion and laceration in 4 cases, hypertensive or cerebral amyloid angiopathy with hemorrhage in 9 cases, infarction area hemorrhage in 2 cases. Among the 14 cases with senile microangiopathy or old hemorrhage associated with multiple lumen infarction, 10 cases were diagnosed as cavernous hemangioma. Signal loss was found in both types of lesions. In addition to SWI (100%), DWI was also highly sensitive (80%). Conclusion: Multi-sequence 3.0T MRI can provide more pathological information for acute and chronic CMHF, and then diagnose, differentiate and predict the progress of disease.
